Dark spots in objects

[superbob]

Hello all!

I'm having a problem with some objects in 3D studio. I'm using U3d's exporter...so I don't know if it's the exporter or Indigo in general



The attached image is a countertop that I have...notice the black corner on it. This is on the countertop no matter what material or what UVW mapping I have. The geometry is clean..all neat quads. This has happend before on other materials, and chaing the UVW has helped...but in this case, it doesn't seem to care what the UVW is set at or if I even have any.

Any advice?

Thanks

Wait...I actually ADDED smoothing groups to it, and it looks fine now. Mmm...usually smoothing groups screw my scene up. Could this be the problem, or is it just a coincedence?
